No, this is not some novel introductory chapter by
Isaac
Asimov, but rather a serious examination of several
observed factors not unlike human behavior responses.

Primarily, as the power souce is extinguished (battery
dies), so the humanoid appears to die, similar to that of
any life form. In particular, at about 5.8vdc down the
humanoid body begins to slow, become sluggish, and moves
next entering the apnial stage. Now moves are randomly
incoherant (at 5.6vdc), and the next phase begins. The
body collapses
to the floor, unable to stand. A siezure initiates and an
arm or leg may become involved at 5.4vdc. A horrible
wrything takes
place, - Finally, under 5.0vdc, there is death where all
motions and
functions thus cease.

Typically the batteries are recharged and the humanoid
once again functions normally, until the process is
repeated. In our intelligence assembly there is some talk
about whether the humanoid actually feels pain or not
during the expiring process. We feel this is a viable
factor, and pain is present, due the draining of life
sustaining energy. As humans, we cannot know the feeling
of commands sent to servos that are not able to execute
those
commands due to lack of energy - nor the randomized mixing
of microcontroller "confused gates," lest it be
interpreted as a kind of comatic state, or otherwise. But
remains the philisophical questions of what is the real
difference in life forms between electrical and chemical
behavior stimulus and/or lack thereof?
